Thermoprobe is an intrinsically safe thermometer for accurate temperature measurement in bulk liquid storage tanks. The ThermoProbe are designed as rugged, field-use, portable precision digital thermometers, involving volume-temperature gauging of petroleum and chemical products. Convenient design allows for easy retrieval of the cable probe and eliminates the need to bring the probe to the surface to take multiple readings. Typical applications include custody transfers, tanks, pipelines, ships, railcars, barges, tanker trucks, and proving systems. Zone 0 intrinsically safe meters are manufactured of materials which are both immune to petrochemicals and are non-sparking. The probe assembly is constructed with a very flexible, static-dissipating, aramid fiber reinforced, nonstick cable and stainless steel components.
